c++ - Gsoap compilation -

i trying write simple hello world gsoap sample. have included http_get plugin also. when compile using :

g++ restservice.cpp soapc.cpp soaprestservicesoap12service.cpp -o server.exe -lgsoap++ 

i follwing errors :

    soaprestservicesoap12service.cpp:(.text+0x0): multiple definition of `soap_encode_string' /tmp/cci3th4n.o:restservice.cpp:(.text+0x0): first defined here /tmp/cc9vrcvb.o: in function `soap_decode_string': soaprestservicesoap12service.cpp:(.text+0x138): multiple definition of `soap_decode_string' /tmp/cci3th4n.o:restservice.cpp:(.text+0x138): first defined here /tmp/cc9vrcvb.o: in function `http_get': soaprestservicesoap12service.cpp:(.text+0x162c): multiple definition of `http_get' /tmp/cci3th4n.o:restservice.cpp:(.text+0x5fe): first defined here /tmp/cc9vrcvb.o: in function `query_val': soaprestservicesoap12service.cpp:(.text+0x141a): multiple definition of `query_val' /tmp/cci3th4n.o:restservice.cpp:(.text+0x3ec): first defined here /tmp/cc9vrcvb.o: in function `query_key': soaprestservicesoap12service.cpp:(.text+0x148e): multiple definition of `query_key' /tmp/cci3th4n.o:restservice.cpp:(.text+0x460): first defined here /tmp/cc9vrcvb.o: in function `query': soaprestservicesoap12service.cpp:(.text+0x150c): multiple definition of `query' /tmp/cci3th4n.o:restservice.cpp:(.text+0x4de): first defined here /tmp/cc9vrcvb.o: in function `soap_get_connect': soaprestservicesoap12service.cpp:(.text+0x152c): multiple definition of `soap_get_connect' /tmp/cci3th4n.o:restservice.cpp:(.text+0x4fe): first defined here /tmp/cc9vrcvb.o:(.rodata+0xc7): multiple definition of `http_get_id' /tmp/cci3th4n.o:(.rodata+0x13): first defined here 

below code

i'm assuming both restservice.cpp , soaprestservicesoap12service.cpp has #include soaprestservicesoap12service.h in header have double definition of functions in httpget.c. can check here similar issue.

it practice not include .cpp or .c files in header files. guess can try remove #include "httpget.c" in soaprestservicesoap12service.cpp , in compilation, add httpget.c source file.

e.g.

g++ httpget.c restservice.cpp soapc.cpp soaprestservicesoap12service.cpp -o server.exe -lgsoap++
